Through the inspection of the team this month, it was found that no. 3 building of the second part of the East District of the Century Shang Courtyard was not strict in waterproof closing, and the closing appeared the phenomenon of opening the mouth of the coil; Zhengshan community 1#, 3# between the garage top surface waterproof empty drum, lap lax; Zhucun Community building 3 roof waterproof closing groove is not plastered leveling, Yin and Yang corner is not additional layer; County hospital apron building kitchen waterproof base treatment rough; Water seepage occurred on the roof of Building 8 in Century New Town, which has been handed in. From the waterproof quality to truly feel the importance of engineering construction quality. Do well, win praise, praise; Do not do well, complaints, not only affect the word of mouth, and a waste of work. The damage was double. Quality can not be closed, corporate reputation, economic benefits are empty talk.

Our project management, the key to do a good job of two management and two innovation: strengthen on-site management, create enterprise reputation; Strengthen cost management and create economic benefits. Every project manager should bear in mind that the life and death of real estate development enterprises depends on the construction period, and the success or failure depends on the quality. We must be clear about the daily interest, cost and benefit of the project under our jurisdiction, always pay attention to the construction progress, quality and construction safety, and fully implement the main responsibility.

In view of the waterproof quality problems found this time, combined with the previous construction experience, we must do the following in the future:

One is to do basic level processing: the first step in the waterproof construction is the basic level processing, which is the most basic procedure of construction management vulnerabilities, if only considering the construction cost, or the construction progress, not according to the construction standard and requirement, ignored the waterproof base leveling process, will lead to the waterproof layer and base is not strong, appear empty drum phenomenon. Once the waterproof layer is destroyed, resulting in water seepage, late maintenance is extremely difficult. 

Second, to do a good job in the construction process control: Waterproof in large construction projects, technical clarificaiton, process quality control does not reach the designated position, very prone to seam is not well set, long side lap width insufficiency, the short edge length less than 500 mm, and the lower level less than one third width long side lap staggered joints, additional layer do not do, asphalt waterproof base oil spilled under construction defects, such as various defects above ultimately affect the overall quality of waterproof.

3 it is to the finished product protection: waterproof layer of subsequent construction process, it is easy to appear repeatedly protection does not reach the designated position, carts when trample damage, backfill RCC damage, such as steel piercing damage, often after the damage is not found in time, once appear ooze water leakage, will increase the repair work, bring the labor, material waste, time delay and economic losses.

In view of the hidden dangers that often appear in the construction site above, I first conveyed the requirements of General Manager Hu on roof waterproof quality and the company's decision to impose a fine of 500 yuan per water seepage point on the submitted projects at the plenary meeting of the branch on 28th, and emphasized the responsibility to the person, so as to improve the quality awareness of all staff. Highlight the importance of waterproof quality, seriousness. Secondly, confirmed the county hospital phase III comprehensive service building roof waterproof quality, experienced several times of heavy rain roof did not appear any seepage water leakage. Finally, all project departments of one branch are required to carry out leveling treatment of basic mortar before waterproof construction, and take 45° Angle treatment at the shade Angle, waterproof closing to take groove or cap flooding. At the same time in the waterproof construction before the technical work, strengthen the process of construction control, do a good job in the protection of finished products, in the construction process to have completed the waterproof protection to do a good job in the protection of finished products, rigorous trampling, no protection construction, effectively ensure the quality of waterproof construction.

"Quality is benefit, quality is life", our construction quality represents the product quality of the whole group. It is not only related to corporate image and corporate reputation, and directly affect our economic benefits. That is why we must keep quality at our core, focus on quality and safety throughout the process, and fully fulfill our primary responsibility.
